“…Similar storage properties at room temperature are also possessed by other titanium-based alloys, such as TiFe [17]. However, their main disadvantage is that they must be activated at high temperatures (400-450 • C) [18]. The modified alloy TiFe 0.86 Mn 0.05 Co 0.05 can store 1.98 wt.…”

The utilisation of hydrogen in ships has important potential in terms of achieving the decarbonisation of waterway transport, which produces approximately 3% of the world’s total emissions. However, the utilisation of hydrogen drives in maritime and inland shipping is conditioned by the efficient and safe storage of hydrogen as an energy carrier on ship decks. Regardless of the type, the constructional design and the purpose of the aforesaid vessels, the preferred method for hydrogen storage on ships is currently high-pressure storage, with an operating pressure of the fuel storage tanks amounting to tens of MPa. Alternative methods for hydrogen storage include storing the hydrogen in its liquid form, or in hydrides as adsorbed hydrogen and reformed fuels. In the present article, a method for hydrogen storage in metal hydrides is discussed, particularly in a certified low-pressure metal hydride storage tank—the MNTZV-159. The article also analyses the 2D heat conduction in a transversal cross-section of the MNTZV-159 storage tank, for the purpose of creating a final design of the shape of a heat exchanger (intensifier) that will help to shorten the total time of hydrogen absorption into the alloy, i.e., the filling process. Based on the performed 3D calculations for heat conduction, the optimisation and implementation of the intensifier into the internal volume of a metal hydride alloy will increase the performance efficiency of the shell heat exchanger of the MNTZV-159 storage tank. The optimised design increased the cooling power by 46.1%, which shortened the refuelling time by 41% to 2351 s. During that time, the cooling system, which comprised the newly designed internal heat transfer intensifier, was capable of eliminating the total heat from the surface of the storage tank, thus preventing a pressure increase above the allowable value of 30 bar.

“…The hydrogenation of TiFe results in the formation of TiFeH 1.04 (possessing an orthorhombic structure with a P 2221 space group) and TiFeH 1.95 (possessing an orthorhombic structure with a Cmmm space group) [30]. After activation treatment, TiFe can reversibly absorb or desorb hydrogen at room temperature while TiFe 2 does notreact with hydrogen.…”

“…Besides, the addition of Cr improves the cycling stability of the alloy material, reduces pulverization, enhances the activation performance of TiFe alloy, and decreases the platform pressure for hydrogen absorption and release [30]. Ce added into AB-type Ti 50 Fe 48 V 2 significantly improved the hydrogen absorption kinetics of the alloys at room temperature in situations where slow and difficult initial hydrogen absorption is known to be a significant drawback of AB-type hydrogen storage alloys because of their passivating surface oxide layers [34].…”

An efficient and safe hydrogen storage method is one of the important links for the large-scale development of hydrogen in the future. Because of its low price and simple design, Ti-based hydrogen storage alloys are considered to be suitable for practical applications. In this paper, we review the latest research on Ti-based hydrogen storage alloys. Firstly, the machine learning and density functional theory are introduced to provide theoretical guidance for the optimization of Ti-based hydrogen storage alloys. Then, in order to improve the hydrogen storage performance, we briefly introduce the research of AB type and AB2 type Ti-based alloys, focusing on doping elements and adaptive after treatment. Finally, suggestions for the future research and development of Ti-based hydrogen storage alloys are proposed.

“…Several investigations have pointed out that the Fe-Ti system is capable of absorbing and desorbing hydrogen [56,57]; however, the Fe-Ti alloys must be activated at relatively high temperatures (400-450 • C) [56]. Nevertheless, the activation of hydrogenation of Fe-Ti is positively influenced when the alloy is subjected to SPD by different processing routes, such as HEBM, high-pressure torsion and groove or cold rolling via the formation of cracks and subgrain boundaries [58][59][60][61].…”

High-energy ball milling was applied to produce nanocrystalline MgH2-FeTi powder composites. In order to achieve a remarkable synergetic effect between the two materials, the amount of the FeTi catalyst was chosen to be 40 wt.%, 50 wt.% and 60 wt.%. The morphology and microstructure of the as-milled powders were characterized by scanning electron microscopy and X-ray diffraction, respectively. The evaluation of the diffraction profiles by the Convolutional Multiple Whole Profile fitting algorithm provided a detailed microstructural characterization of the coherently scattering α-MgH2 crystallites. Differential scanning calorimetry experiments revealed two overlapping endotherms corresponding to the dehydrogenation of metastable γ-MgH2 and stable α-MgH2 hydrides. Isothermal hydrogen-sorption experiments were carried out in a Sieverts-type apparatus. It was established that the MgH2-40 wt.% FeTi powder is capable of absorbing 5.8 wt.% hydrogen, while extraordinary absorption kinetics were observed for the MgH2-50 wt.% FeTi alloy, i.e., 3.3 wt.% H2 is absorbed after 100 s.
